Antoine Pierre Soulard (November 16, 1766 – March 11, 1825) was an early settler and government official of St. Louis, Missouri.

[1][2] With the French Revolution, and the subsequent Reign of Terror, Soulard fled his homeland for the United States.

He traveled across Pennsylvania on horseback, then floated down the Ohio River on a keelboat, eventually arriving in Ste.

[2][6] Trudeau added to Soulard's responsibilities, appointing him to the position of adjutant pro tem of the lieutenant governor on October 30, 1795.

Soon after this new appointment, Soulard married Marie Julia Cérre, the daughter of a wealthy merchant and fur-trader, Jean-Gabriel Cerré.
